chapter 1 vocab

2. force-A push or pull up on one object by another object that is touching it.
7. of conservation of momentum-A principal stating that the total momentum of a group of objects stay the same unless outside forces act on the objects
8. motion-Any Motion in which an object is moving along a curved path
9. force-The combination of all the forces acting on an object.
11. forces - Forces acting on an object that combine and form a net force that is not zero
13. The tendency of an object to resist the change in its motion
14. push or pull up on an object.
15. first law of motion - law that states that if the net force acting on an object is zero the motion of the object does not change
17. - the gravitational force exerted on an object
18. -A measure of how hard it is to stop a moving object

1. amount of matter in each object .
3. pair-The forces two objects apply to each other
4. force-In circular motion a force that acts perpendicular to the direction of motion towards the center of the Curve
5. forces - Forces acting on an object that combines and form a net force of zero
6. - attractive force that exist between objects that have mass.
9. force-A force that is one object applies to another object without touching it.
10. third law of motion - law that states that for every action there is equal in opposite reaction
12. A contact force that resist the sliding motion to two surfaces that are touching.
16. second law of motion the law that states that the acceleration of an object is equal to the net force exerted of an object divided by the object's Mass
